package/v4l2loopback: drop _CPE_ID_VENDOR

Commit 1edb9d691dec (package/v4l2loopback: add
V4L2LOOPBACK_CPE_ID_VENDOR) added that variable, but set to its default
value.

This is however not required to define a valid CPE ID, as it also
defines a non-default CPE_ID_PREFIX.

Drop V4L2LOOPBACK_CPE_ID_VENDOR now.
